Answer: (i) It is made up of tiny soil-particles without air spaces. The soils of Peninsular India are formed by the decomposition of rocks in situ, i.e. Soil Taxonomy has changed since the last rule rewrite. A sticky, bluish-gray subsurface layer of clay found in some waterlogged soils. The size of soil particles in clay size is less than 0.2mm. It is poorly aerated because the tightly bound clay particles leave little space in between to trap air. Properties of clayey soil: * Plasticity - sticky, the ability to form and retain the shape by an outside force, has a unique "crystal" structure of the molecules, plate like, flat, 2 dimensional, water affects it. Choose the right answer from the four alternatives given below: Question 1(i). Effects: Makes land unsuitable for cultivation. Clay soil is hard work and has the problem of poor drainage, hence flooding in the rain and baking hard as concrete in the sun. Loamy Soil.
